TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Dec. 5, 1916.

Application filed April 6, 1915. Serial No. 19,470.

To all whom it may concern:

Be itknown that we, HUBBARD N. J OSLEYN and JOHN W. KonRNER, citizens of the United States, and residents of Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

Our present invention relates principally to type bar mechanism for typewriting machines and its main object is to provide an improved construction of type bar and mounting for the same.

To the above and other ends our invention consists in the features of construction, combination's of devices and arrangements of parts hereinafter described and particularly pointed out in the claims. I

In carrying out our invention we provide for a cheap construction of type bar and mounting by making the type bars of sheet metal and mounting them on a slotted support or segment on a common fulcrum or wire. One disadvantage in prior constructions of this general nature has been that in order to dismount or remove one type bar it was necessary to dismount or disturb all the other type bars because the whole set of type bars have a common support. 1 Also there was the further disadvantage that the bearings became rapidly defective by reason of the sharp cutting edge of the sheet metal type bar grinding into the fulcrum wire at its point of connection therewith. These disadvantages are avoided in our new and improved construction by providing an individual bearing sleeve for each type bar, said bearing sleeve not having the tendency to cut into the fulcrum wire to the same eX- tent as the sheet metal type bar itself, and further by providing a detachable connection between the type bar and its bearing sleeve so that the type bar may readily be removed from the common fulcrum or pivot device and replaced either by itself or by another type bar without disturbing the other type bars of the set. The present construction is comparatively inexpensive and has been found in practice to be quite ethcient both in respect to efliciency of operation and in the readiness and facility with which the parts may be assembled. and disassembled.

Our invention will be described in detail in connection with the accompanying draw- 5 ings wherein Figure 1 is a side elevation of a type action embodying our present invention. Fig.

2 is a fragmentary front elevation, partly in section, of a type bar segment embodying Our present invention may be applied to a typewriting machine like that shown in 1 the co-pending application of Bond and J osleyn, Serial No. 18,987 filed April 3, 1915, which has matured into Patent 1,197,336, dated September 5, 1916, and wherein a seg- 7 mental type bar support 1 is provided with a forwardly projecting curved portion 2 which is formed with a series of kerfs or slots 3, these slots being radial in respect to the printing point on the front face of a 8 platen 4. The portion 2 also has in its front face an arcuate slot 5 in which is seated a pivot device in the form of a segmental fulcrum or pivot wire 6, said wire being circular in cross section and being detachably 8 heldin place by clips or fingers 7, said fingers being secured by screws 8 to the front face of the portion 2 near its ends and engaging at their free ends with the wire 6. This wire provides a common fulcrum for 9 all of the type bars 9 which are arranged in a segmental series or set. The type bars are preferably of sheet metal and each is secured to its free end with a type block 10 provided with two types, these types being 9 separately brought into use by shifting the segment in any suitable way as by the mechanism disclosed in said Bond and Josleyn application. A type rest 11 which normally supports the free ends of the bars is shift- 1 able with the segment 1. Before describing in detail the pivotal end and mounting of the type bar wherein our invention mainly resides, the actuating devices for the type bars may be briefly described. Each type 1 bar is connected by a detachable link 12 with 7 machine.

The type bars are adapted to be separately forced or sprung into and out of place on the fulcrum wire so as not to disturb their fellows. Preferably instead of bearing directly on the wire 6 each type bar bears on a rotary bearing member or sleeve 21, there being a separate sleeve or collar for each type bar. These sleeves are preferably machined. They are of such width that they fit loosely into the slots 3 when strung along the fulcrum wire 6 on which they bear, and the construction is such that the sides of the slots 3 are engaged loosely by the sleeves which are thereby held in register with their slots and prevented from lateral displacement lengthwise of the wire 6. In assembling the sleeves on the fulcrum wire it is preferable to insert the fulcrum wire 6 in one end of its seat or slot 5 and then to work it around gradually lengthwise through said slot. Intoeach slot 3 the associate s 'eeve 21 is inserted by any convenient means as by a tweezer in position to be picked up by the fulcrum wire as it is pushed along. The fulcrum wire and the sleeves having once been assembled on the segment 1, it will not be necessary to disturb them in putting on and removing the type bars. To this end each type bar at its pivot end is formed with a round or circular opening 22 which will receive the associate sleeve 21 and frictionally grip or grasp the same. At the side of the opening 22 toward the type end of the type bar the type bar is formed with a long slit or kerf 23 which connects with the opening 22, and at the opposite side from the kerf a comparatively wide mouth or entrance2 to the opening 22 is provided, this mouth having flaring edges or sides 25. At the outer ends the distance between the edges 25 is greater than the outer diameter of the sleeve 21 but at the innerrends of said edges where they join the opening 22 they are spaced apart slightly less than the sleeve diameter. This requires that the jaws 26 and 27 formed in the type bar by the continuous opening made up of the slit 28, round opening 22 and mouth 24, shall be resilient or yielding so that the type bar may be sprung into place on its sleeve. In Fig. 4: the type bar is shown detached. In mounting it in place the pivot end is passed rearward through the associate slot 3, the mouth 24 passing freely over the sleeve 21 until the narrow. end of the mouth is approached when its sides will contact with the sleeve and will require that the bar be forced backward, causing the jaws 26 and- 27 to separate or be sprung apart slightly until the mouth 24L. has passed the sleeve when the jaws will spring together and the sides of the opening 22 will grip the sleeve with sufficient friction to cause the sleeve and type bar to act as a single unitary device during turning movements of the type bar. After the type bar has been thus assembled on its sleeve it is only necessary to connect its link 12 with the sub-lever 13 to make the bar ready for actuation by its key lever. In removing a type bar its link is first detached from its sub-lever and then the type bar is pulled off either by hand or by the aid of pliers, the jaws being thus forced apart sufficiently to permit the bar to be pulled off its sleeve 21.

It will be observed that by our present invention we provide a fulcrum wire having individual type bars fulcrumed thereon, each type bar having means for affording a removal of the type bar singly from saidwire without disturbing the other type bars or the wire; that the type bar may be sprung on its pivot device or fulcrum wire; that preferably between the pivot device and the type bar is interposed a bearing member or sleeve which is rotatable on the pivot device and on which the type bar is directly'sprung, the type bar thereby having a pivotal connection with its pivot device or fulcrum wire; that the sleeve while rotatable on the pivot device is held in its guide slot against substantial lateral movement; and that the type bar is guided by the guide slot or radial slot and has a fixed relationship with its sleeve during printing movements, the type bar and sleeve acting as a single rigid member or device.

Preferably a center guide (not shown) isprovided for cooperating with the type bars at or near the printing point.

Various changes may be made without departing from our invention.

What we claim as new and desire to claim by Letters Patent, is r 1. In a typewriting machine, the combination of a fulcrum wire, individual type bars fulcrumed thereon, key controlled actuating devices for said type bars, and means for providinga bearing for the type bar that completely surrounds the pivot wire and for affording a separate removal of said type bars from said wire without disturbing the other type bars or the fulcrum wlre.
